Highly diastereoselective synthesis of novel 2,3,4-trisubstituted chromanes via the reaction of 3-nitro-2-(trihalomethyl)- and 3-nitro-2-phenyl-2H-chromenes with 1-morpholinocyclopentene
The reaction of 3-nitro-2-trifluoro(trichloro)methyl- and 3-nitro-2-phenyl-2H-chromenes with 1-morpholinocyclopentene under the conditions of kinetic or thermodynamic control led to the formation of products due to enamine addition at the C-4 atom of chro
